You need to file the years that have not been filed.
- Start by finding out what was reported to the IRS.
- To see what was reported to the IRS, go to Get My Transcript and request a Record of Account type of transcript for 2017, 2018, 2019 and 2020.
- Only report the income from 2017 in 2017, income from 2018 in 2018, etc.
- Next, start with the oldest year. Purchase the tax software for each year because the rules change that much from year to year. To file prior years, go here to purchase the prior year CD/Downloads.
- Your filing status without children is single if you were not married on December 31 of that year.
- Use your current address so that any correspondence will come to you. The address on your W-2 will be from the year it was issued.
- Last, file 2020. To report the stimulus payments, report 0 in each stimulus payment if you did not receive it.
- To do this in TurboTax, in the search, type stimulus and click the Jump to link.
