Retirement tax questions

we divorced in 2013. So it’s taxable for both of us. And she has never filed on her end. And I’ve been receiving the 1099-R and taking the hit because we’re not having enough taxes taken out during the year only $220 in state and only $485 in federal for the year. So even though I would get the alimony credit it would be more if we had the proper amount of taxes come out during the year. But when we filed for divorce she wouldn’t sign the papers unless I agreed to continue to give her my retirement she’s getting my retirement (full retirement and my disability), my daughter was still young and I was still working so I agreed not realizing how screwed I would be later on (now 10 years later). I didn’t know at the time that the law was that she was only entitled to up to 50% of the taxable amount and none of my disability. now my health has declined and I’m looking into retirement with SSI and I can’t afford to and lawyers are telling me that it will be hard to try to get a modification now to try to get back what is rightfully mine. Luckily though she mandated in the divorce that we put a set amount which is what my full retirement was at that time. And you know that with COLA the amounts have drastically increased to my benefit so I am making changes to get that portion back. As well as going to get reevaluated for my disability. I’ve only had the one check up when I first got it. I’ve never been back to get reevaluated and my health has drastically declined since. So I’m confident that my disability percentage will increase. I will fight to at least get my disability back from her as I cannot afford to retire with out it and with my health I cannot afford to work. But I just wanted to know how I come out ahead if I should continue to receive the 1099-R my self and claim the income tax then claim the credit or have them send her a 1099-R directly to her as if I never received the income. Does it equal out? Or is one way better than the other? It sounded like you said they would be the same. I just want to verify that is what I understood before I make the change to have the 1098-R go to her. Because yes, it would be less headaches
