@leeloo , seminole70-gmail is referring to the anti-abuse provision that treats QCDs as taxable until a sufficient dollar amount of QCDs has been made to offset deductible contributions made in or after the year that the individual reaches age 70½. So claiming QCD is not prohibited, it's just that such QCDs are taxable and TurboTax can't, and may never, handle this situation.
Handling this would require TurboTax to track basis in deductible contributions made in or after the year one reaches age 70½, subtracting from that basis any QCDs made, and only treating QCDs as nontaxable once that basis has been reduced to zero.
This provision in the tax code effectively makes one have to make a life choice between making deductible traditional IRA contributions in or after the year they reach age 70½ or making QCDs.
