After you file

The IRS did implement it  BUT ONLY if you efiled the original return  and CAN efile the amendment then the direct deposit can happen.   Sorry to say the TT program only allows efiling of amended returns for the current tax year only and only up until the efile season closes each year in October.   A 2021 amended return must be mailed in  and the refund check mailed to the address on the 1040X.
