After you file

Although the IRS accepts 2019 e-filed returns, TurboTax does not allow a previous year original return or a previous year amend to be e-filed.  When you amend 2019 using TurboTax you must print and mail the retrun.

Even though your husband did not file for 2019 yet, the first and second stimulus can be claimed on the 2020 income tax return and will be added to the refund or deducted from any tax owed.  Here is how to claim the stimulus on the 2020 return.  When you answer the questions, TurboTax will determine the amount that you are owed for the first two payments.

At the top of your tax return select Federal Review

That will take you to this screen where it asks if you have already received your stimulus payments.  If you received the first or second payment already, then select Yes and fill in the information.  

When that page is correct, you refund will be adjusted correctly.
