Will my adjusted gross income for 2019 which includes his salary hurt me?

No. The IRS requires your 2019 AGI to verify your identity for e-filing. If you're paper-filing your return, you won't need your AGI because those are manually processed.

You can obtain a transcript of your tax return from the IRS if you need it. To obtain an IRS Transcript, click the link to get started. 

Under the new legislation, if your earned income was higher in 2019 than in 2020, you can use the 2019 amount to figure your EITC for 2020 (if applicable). This temporary relief is provided through the Taxpayer Certainty and Disaster Tax Relief Act of 2020.

TurboTax will walk you through the steps and allow you to choose 2019 earned income or 2020 earned income.  Try it both ways to see which is best and then be sure you verify which you should use.  Then confirm you have selected the correct response for the year you want to use. It is ready and functioning correctly in TurboTax. See the steps to entry and the image below for assistance.

The earned income tax credit (EITC) is calculated on a scale based on marital status and number of dependents. If you fall into the mid-range of income, in both tax years, the outcome may not vary much at all.
