If your father's only income is Social Security he is not required to file a tax return. What transcripts are you referring to? If your dad has been getting Social Security he receives a SSA1099 every year in late January.
And....the current online software is only for 2020 returns. There is not a way to use TurboTax to file a past year return for free even if you have taxable income to enter.
A past year return has to be prepared by using the purchased CD/download software. And the return has to be printed, signed and mailed. It cannot be e-filed.
Please explain why you think you need to file returns for Social Security for your father for the past three years so we can understand and be more helpful. It is not clear what you are trying to accomplish.
