Filed 1/14, Accepted 1/17 - Is 3-Day Processing Normal for 2024 HOH Return? Still in "Return Received" Status

I submitted my taxes on January 14th and got the acceptance notification on January 17th. First time filing this early and wondering if 3 days for acceptance is normal? Should I be worried about delays? I just checked my refund status on the IRS website and got this message: "We have received your tax return and it is being processed. It can take up to 3 weeks to process your return if you filed electronically, or 4 to 6 weeks if you mailed your return. However, processing may take longer under certain circumstances." The status shows "Return Received" but both "Refund Approved" and "Refund Sent" are still pending with question marks. The site also references "Tax Topic 152, Refund Information" which I'm not sure if that's good or bad? For context, I filed as Head of Household for Tax Year 2024. This is my first time filing so early in the season, and I'm getting anxious about when I'll actually see my refund. Is this normal processing time or should I be concerned about potential delays? Has anyone else who filed around the same time started seeing movement on their refund status?
