I am not sure how the DRT information can be changed after it’s imported into the FAFSA, but there must be some items that can be changed. I say this because the “information changed “ flag is active for current FAFSAs. Something got changed on yours, but you don’t need to worry about it … just turn in what was requested. However, I am surprised they are requesting a paper copy - I would request the IRS tax transcript in the case of a change after DRT. I am guessing whatever can be manually changed must be minor, and they are requesting the paper copy because they have to collect tax information by regulation in this case.
