Hi smperry,
When entering a contribution to an individual 401k, and you are over 50 and made a catch up contribution, you need to enter the elective deferral amount and the catch up contribution amount separately. To do so in TurboTax Self Employed:
- Click Federal on the left side.
- On the Your income and expenses page, click edit next to Self-Employment Retirement Plans
- On the Self-Employed Retirement Plans page, click Yes
- In the Individual 401(K) section, enter the amount of the Elective Deferral you made (the maximum amount for 2018 is $18,500 as you know). Only enter the maximum amount in this field.
- Enter the amount of Catch-Up contributions you made (up to $6,000 for 2018) in the Catch-Up Contributions field
