@subhra_roy We cannot tell what version of TurboTax you are using. As stated, if your only income is Social Security you do not even need to file a tax return, so you could just abandon the account and forget about filing.
But if you use TurboTax and you file a tax return, you will be charged for the version of the software you use. regardless of whether you owe or are getting a refund. Your TurboTax fees are not based on whether you are getting a refund; your fees are based on the software you actually USE. It sounds like you are trying to use a paid version of the software----unnecessarily.
If you have not paid, then just clear the return, or abandon the TT account and pay nothing. You do not need to file a tax return if your only income was Social Security.
