My wife is a sole proprietor (58 years old) with an LLC. She receives a 1099-NEC.
She has only had a SOLO 401K until 2025, and never had a problem with Turbo Tax reporting. i.e. in 2024 tax year she contributed $30K (including catch up) plus a company match of $15K, totaling $45K. Her income was 65K. All report properly as $45K was deducted from income.
This year, 2025, her income was $70K (profit = $66.8K). She added a ROTH Solo 401K and mixed the contributions as follows: $31K employee contribution, 11K went to the Solo 401K, and $20K (12.5K+ $7.5K catch up) to the Roth Solo 401K. An additional $15K was made as Employer contribution to Solo 401K. So, the math says $26K was contributed to the deductible account (not the ROTH). Right?
Turbo tax appears to only be accepting $23,414 as a deductible amount. Why doesn't TT show $26K ($15 employer contribution + $11K employee contribution) in the summary screen "Less common Business Situations; Self-employed Retirement"?
