On where’s my refund . It showed one bar with message “We have received your tax return and it is being processed” with a tax topic 152 . Now there is no bar still has the same message but no tax topic . Should I be worried ?

IRS expert here - the disappearing bar and tax topic 152 is actually pretty common. When the bars disappear but you still see the processing message, it usually means your return moved to a different processing department. This isn't necessarily bad news - could just be verification or review. The best way to know exactly what's happening is to check your transcript. I've been helping folks lately with taxr.ai (https://taxr.ai) - it reads your transcript and tells you exactly where you are in the process and if there are any holds. Way better than trying to decode WMR or calling the IRS tbh.

Is there any update? It’s been 10 days since you posted here. Tax Topic Code 152 means your refund is being processed and generally within 21 days after IRS received your return, over 90% tax filers receive it.    Unless you have Code 570 (account on hold to review), you’re fine. I would advise you to contact IRS if passed over 21 days or a month without any update. First time call $5 discount using claimyr https://join.claimyr.com/49a083

To all those having trouble reaching a human at IRS. I just ran across this video that gave me a shortcut to reach a human. Hope it helps! https://youtu.be/_kiP6q8DX5c

Don't worry too much! The disappearing progress bars on Where's My Refund are super common this time of year. When the bars disappear but you still see the processing message, it usually just means your return moved to a different stage or department - not necessarily a problem. Tax Topic 152 disappearing is also normal as returns progress through the system. That said, if it's been more than 21 days since you filed, it might be worth checking your account transcript on the IRS website to see if there are any issues or holds. The transcript will show you exactly what's happening behind the scenes with codes and dates. If you're really concerned after checking your transcript, you can try calling the IRS, though wait times are brutal right now. Most of the time though, these changes are just part of normal processing. Keep checking WMR every few days for updates!
