Solo 401k error - worksheet

Trigger2 — Wed, 11 Feb 2026 05:20:25 GMT

I am trying to file my taxes but TT won't allow me to do so. It says I have an error on the Keogh/SEP/Simple worksheet. I contributed the maximum amount to my solo 401k of $22,500. I also contributed the over 50 amount of $7,500. And my business contributed another $33,000. The worksheet shows the amounts on lines 6a, 6c and 6e. However, TT shows I have an error on line 6a and that it shouldn't be over $22,500. It's not - it is exactly $22,500. I have re-entered it several times but the error persists.

And it won't allow me to e-file unless I clear the error, despite the fact that it appears correct. I am open to suggestions. I suspect there is another place where something is not correct, but I cannot seem to find it. I've been through the questions several times. And been through the business income section several times. I am at a loss of how to correct the error (which doesn't appear to be an error to me).

Thanks

This is a known problem. The following thread provides a workaround:

This worked. Silly way to handle it - just needs to be fixed.

But thank you for the quick response which allowed the returns to be transmissted!

I am working on my tax return reviewing an error 2024 Keogh/ SEP worksheet, individual 401k section and this bug still seems to be active from past years. I have input $23,000 on line 6a and the $7500 catch up contribution on line 6c, totaling the max $30,500 on line d, but keep getting the error on line 6a. Any ideas?
