Deductions & credits

Hi @Opus 17 ! 

I really appreciate the prompt response. I confirm that the insurance I have is HDHP with HSA. I got both through my employer and just double checked on our benefit election page. I'm 99% positive that I will be eligible to apply the last month rule. However, I had just filed my 2019 return with the incorrect HSA excessive contribution amount, should I amend the return to correct this mistake? (😅 )
