I’m having difficulty filing a Ga.State income tax form.

In 2022 my family and I sold vacant land in Ga. we where non-residents and the closing attorneys withheld 3% of the sale price. My sister who had an income of 65k told me her CPA was able to get back all her withheld sales tax. When I fill out the GA. Income tax form on the TurboTax program it tells me we owe money. 
My sister says that her CPA said Ga. has very generous tax withholding refunds for people over 65 years old. We are both over 65 and my wife and I file jointly with double the income of sister who is single.

I wanted to add we never got a answer to our question although we did have a couple of replies.

I called the CPA of 30 years my sister uses and he assured me the TurboTax program was wrong because it keep transferring SS income from the federal side to the Ga. return and begin having us look for any form or worksheet that ends in “NR”(non-resident) that we could enter the taxable amount minus the cost basis. 
It appears your tax expert help day do not help us very disappointed…You seem to want us pay you $99 to point out your tax software problems. I can do that for free right here……????
