23 Has anyone tried contacting the IRS through their website? I lost some tax documents too and read that they have an online messaging system now?? Trying to avoid calling them if possible...

I went through this exact same situation last year! Don't stress too much - you have several good options. The IRS Get Transcript online tool is definitely your best bet. Log into your IRS online account and request an "Account Transcript" for 2020. It will show your Economic Impact Payment amount clearly. If you can't access it online (sometimes the identity verification is tricky), you can call the IRS and request they mail you the transcript. Yes, the wait times are brutal, but it's the official documentation you need. Your phone photo of the deposited check is actually great backup documentation to keep with your tax records. While the transcript is the "official" source, having that photo shows you're not just guessing at the amount. One tip: if you use tax software, most programs will ask you about stimulus payments received and help calculate if you're owed additional credit. Even without the notice, as long as you have the correct amount, you should be fine.

Just wanted to add that if you're just doing simple buy/sell transactions on major exchanges, TurboTax Premium is probably fine by itself. I've been using it for 3 years with my Coinbase and Gemini accounts. The key thing is downloading the transaction history CSV files from each exchange at the end of the year. TurboTax has an import feature that usually works for the major exchanges. Just be careful about the cost basis - sometimes the exchanges don't track it correctly if you've moved coins between platforms. Also, remember that crypto-to-crypto trades are taxable events too! If you traded BTC for ETH, that's a sale of BTC and a purchase of ETH. A lot of people miss this.

One thing nobody's mentioned - if you received any staking rewards or interest on your crypto, that's considered ordinary income at the fair market value when you received it. Different from capital gains from selling!

Did you file the original 6 year old return electronically or on paper? If on paper, I'd recommend calling the IRS to confirm they've fully processed it before filing an amendment. In my experience, if you file an amendment too soon after a paper return, things can get really messed up in their system.

Just went through something very similar! Filed a 2018 return late last year and then realized I'd forgotten about estimated payments I'd made. The good news is you can definitely still amend since you just filed the original return. One thing I learned the hard way - make sure you have solid documentation of those estimated payments before you amend. I thought I remembered making four quarterly payments but when I dug through my old bank records, I'd only made three. The IRS will want to see proof like canceled checks or bank statements showing the payments went to the Treasury. Also, don't stress too much about the timing. Since you just filed the original return, you have plenty of time to get the amendment right. Take a few weeks to gather all your documentation and double-check everything before sending in the 1040-X. Better to be thorough than to have to amend your amendment!

Pro tip: get your congressman involved. Worked for me after my 3rd letter

Ugh, I feel your pain! I'm on my third 60-day letter for 2022 too. What's really annoying is they keep asking for the same documents I already sent. I started keeping copies of everything with delivery confirmations just to prove I sent stuff. The whole system feels broken honestly. Have you tried getting your account transcript online? Sometimes that shows what specific issue they're actually reviewing.

Side note: Even if your CPA won't budge, YOU are the one signing your tax return, not them. The signature line says "Under penalties of perjury, I declare..." so ultimately it's your responsibility. If you have reasonable basis for your position (which it sounds like you do), you can override your CPA. They work for you, not the other way around. Either they file it the way you want with proper support, or you find someone who will. Just document your reasoning and keep support for your position in case of audit. Tax positions don't have to be 100% certain to be valid - they just need substantial authority.

Miguel, I completely understand your frustration! I went through something very similar last year with my beach condo rental. My CPA was also insisting on Schedule C treatment, but after doing my own research and getting a second opinion, I was able to demonstrate that Schedule E was the correct classification for my situation. The "substantial services" test is really the key here. From what you've described - providing furniture, parking, and basic essentials - that sounds more like typical rental property amenities rather than hotel-like services that would trigger Schedule C treatment. I'd strongly recommend getting that second opinion from a CPA who specializes in rental properties. Bring documentation of exactly what services you provide versus what you don't (no daily cleaning, no meals, no concierge services, etc.). The difference between paying SE tax and not paying it is significant enough to justify the cost of a consultation. Also keep in mind that if you do end up needing to switch CPAs over this issue, it's not necessarily a reflection on their overall competence - some practitioners are just more conservative or less familiar with the nuances of short-term rental taxation. The important thing is getting the classification right based on the actual facts of your situation.
