Roth 401k contribution for over 50

I understand that a sole proprietor may contribute up to 23000 to a Roth 401K with an additional 7500 catch up contribution for those over 50. When I try to enter an amount over 23000 in Home and Business in the "self employed retirement plans" section of "Business income and Expenses" the additional amount over 23000 up to a total of 30500 is not allowed.

How is this to be handled?

Thanks, Marcus

In 2024 TurboTax, there are separate boxes for the entry of the regular Roth 401(k) contribution ($23,000) and the Catch-up Roth 401(k) contribution ($7,500). Still, your contributions are limited to net earnings from self-employment. Net earnings are net profit minus the deductible portion of self-employment taxes. Also, make sure that you have entered your birthdate correctly, with the year of birth being 1974 or earlier.

Thank you for the prompt and thorough reply. I'm still a bit confused:

I now see the boxes you mentioned but could you tell me what line and form shows the net earnings figure used to establish the maximum contribution? Is it AGI?

"Net earnings are net profit minus the deductible portion of self-employment taxes."

Net profit is on line 31 of Schedule C. The deductible portion of self-employment taxes is on line 15 of Schedule 1 (which comes from line 13 of Schedule SE).
