Retirement tax questions

Does this still hold true for 2020 tax purposes?  I retired from the military last year and paid my ex-wife (with a personal check) for 6 months of her portion of the military retirement.  The military caught up and paid her via direct deposit for the other 6 months.  My 1099R shows me getting ALL of the retirement income and paying ALL of the taxes.  Is there a way I can deduct her portion from my gross distribution and recoupe the taxes I paid on her portion of the retirement?
