I had my previous job 2015 through August 2018. Near the start of the job, I remember contributing something like $200 to an FSA. I regretted my decision (since I hate dealing with FSA complications) and didn't contribute further. I think that $200 may have carried over through the years being under the $500 limit but I'm not sure. I basically forgot about it having not used any health care and am not sure I have any way of logging back into it.
I started my new job October 2018. I'd like to enroll in the high deductible plan with an HSA, but I'm wondering if this FSA could in any way disqualify me in my new job. I think it's not possible, but I read various pages mentioning grace periods for FSAs, and I'd just like to confirm for sure that I'm qualified to open an HSA.
