How do i fill in 1040 line 36?

To add, change or delete a current year federal tax refund to next year's taxes before you file your tax return -

• Click on Federal Taxes (Personal using Home and Business)
• Click on Other Tax Situations
• Under Additional Tax Payments

Or enter apply federal refund to next year in the Search box located in the upper right of the program screen. Click on Jump to apply federal refund to next year

The amount applied to next years taxes will be shown on Form 1040 Line 36

Your idea worked!  This feature is hard to find.

I owe money but it shows an amount to apply to refund and adds it to the amount i owe.  I can't access the field because I'm not getting a refund

Where does it show amount to apply to refund?  What does your actual 1040 return show?

oh, is it for a refund amount from your 2019 return to apply to this year 2020?
