n January 2019 I made a $5000 contribution to my HSA to fully fund it for 2018 and filed my taxes for 2018. In February 2019 I filed for my Social Security Benefits. I did not take Medicare Part B because I was still working. I retired in Sept 2019. I now realize that my Medicare Part A started on September 1, 2018. I know that my prorated contribution amount for Jan. 1, 2018 to Sept 1, 2018 is $5266.64. What is the best way to handle the excess contribution of $2633.36 ? do I request a return for the Excess Contribution and Amend my 2018 tax return ? or just withdraw it and pay the taxes in 2019 ? What is ersiehst and cleanest to do ?
