Timing mismatch of 529 distribution shown on 1099-Q and Education expenses

My son's distribution (he was the recipient) from the 529 account shows payments intended for the spring 2022 semester (distribution was made on 12/29/21 and received by the institution on 1/6/22).  TT states that this should be taxable income in 2021.  This seems like just a timing issue and should be correctable and applied in the 2022 return.
