Retirement tax questions

Ask your ex if she could help.  It would be good for her.  If you get your payments directly from DFAS she can stop paying you.   Do you know if she deducts what she pays you on her tax return?  If you haven't been reporting it all these years why are you asking about reporting it now?  What did the tax preparer do with it?  Does it show up anywhere on your 2021> returns?
