I was on the phone for over an hour with a Turbotax CPA yesterday, and she could not figure out the problem and is "working on it". I have exactly the correct 2025 maximum amounts contributed to my solo 401(k) for people over 50, including $5500 catchup in a Roth 401(k). Turbotax is saying something about how this brings my total above the allowable amount. With all the errors in the area of contribution limits in the software already reported this year, I assume that this is one that they're still working on or even haven't found out about yet. The CPA lady seemed quite frustrated, and she ended up having me send my tax file to her from the desktop so she can work on it. Don't know why they keep having so many software errors.....
