2nd year with an HSA and I now see that I messed up last years return. We did not contribute more (excess contribution) but I entered info incorrectly. On the 8889 line 2, i didnt realize that the contribution was already entered from my w2 so i entered the amount again. Going back i now see that it says "do not include employer contributions". I made no personal contributions, they were payroll only. Am i thinking that correctly? and if so, i assume i need to do an amended return for last year. And i also paid extra tax on the "excess contribution" that i did not make.
So for this year, its asking me for my excess contribution from last year from the 5329 of the return. That should be zero but of course, it isnt. For this year return, should i put 0 knowing that i need to file an amended return for last year by mail or should i just show the amount, then file, then do two amended returns?
