Are you receiving any compensation at all from DFAS? I ask because I doubt it if you are classified with a 100% disability rating. With that rating DFAS pays nothing and the VA (Veterans Administration) pays everything. With the VA Pay you don't receive any type of tax reporting document because VA disability pay is not taxable or reportable on any tax return.
Par chance did you retire in 2018 or earlier and start receiving your disability pay any time "AFTER" you received your first retirement check from DFAS? If yes, do you have the letter from the VA that explicitly states your disability pay is retroactive back to your retirement date, or any other date?
