I just received my 5498-SA from my HSA bank and the total contribution differs from the box 12c on my W2. I made no employee contribution so the entirety of the contribution were from my employer, and W2 box 12c and 5498-SA amount should match up but didn't.
I had contacted my employer and they are issuing a W2C to correct the box 12c to the correct number reported in 5498-SA. I had already filed my tax return using the original W2 12c amount.
Both the correct and incorrect amounts were definitely under the contribution limit.
Do I need to file an amended return? Do I contact IRS directly?
