I postponed my tax bill payments so I could make contributions to my 2019 IRA with the intention of lowering my tax owed. But 2019 contributions in 2020 are not lowering what I owe for 2019. I thought it would. Even though submitting taxes until July is an option, Is it that I can't lower my liability by making contributions to 2019? Or should I be able to do that? It does lower if I make the direct contribution to 2019. But that is not the case since I'm making the contribution in 2020.
