Prepared the whole 1040 Tax return and was getting ready to efile. I realized that I need drivers license info so I got out of file to come back later. Now file error message unable to open tax file. Very uspet.
If the file is a tax data file for tax year 2021 and Not a PDF, then it is either corrupted or you will have to copy the file to the TurboTax folder in the Documents directory on your C:\ drive.
Also check to see if there is a backup data file in the TurboTax folder for 2021 which will have a tilde (~) at the beginning of the file name. If there is such a file use that to open the tax return.
If the 2021 file is corrupt then you will have to start a new tax return using the 2021 TurboTax program.
This all assumes you are using the TurboTax program for Windows.
Yep, re-entered all the data.
