The calculation when checking the "Maximize Contribution to Individual 401(k)" box under "Individual and Roth 401(k) Plans" is still using the 2019 maximum elective deferral amount of $19,000 instead of the 2020 amount of $19,500.
If you view the supporting "Keogh/SEP Wks" form, Part III Step 9 enters the 2019 amount of $19,000:
However, if you right click on the Step 9 amount and select "About Step 9 Elect def, sp", the On Demand Tax Guidance shows the correct $19,500 amount for 2020.
I can override this amount in the worksheet to put in the correct amount, but this should be fixed for anyone else who is relying on TurboTax to calculate their maximum contribution.
