So in 2024 my employer funded my HSA by $6000. I quit before December 2024. And a few days ago I decided to self-fund HSA $2300 to reach the maximum, not knowing that HSA is pro-rated by how many months I've had the employer's insurance. I realized almost immediately that I overfunded it by $692 and I made the withdrawal as soon as possible.
The question is, now how do I report it on the tax form? Do I say I funded it by $2300 and then there'll be another form to say I withdrew $692 later, or do I say I funded $1608? I just went through this step in FreeTaxUSA and in the preview I see no mention of $692, it still used $2300 in Line 2 of Form 8889 so I'm wondering how this gets sorted out so that I do not get taxed the penalty.
Thanks!
