I am 23 years old and graduated from college in May 2018 (i.e., a fifth-year full-time student through May 2018 in a master's degree program). My parents provided the majority of my support throughout 2018 and have claimed me as a dependent for 2018. I started working full-time employment on September 20, 2018, and began making monthly $50 contributions in October 2018 to an HSA through my employer (W-2, Box 12, Code W = $150). Turbo Tax won't let me finish (and electronically file) my 2018 return because as a dependent of someone else I was not eligible to make contributions to a HSA during 2018 -- a tax code requirement that was unbeknownst to me until now. Turbo Tax says I have Federal Form 8889 errors that need to be corrected before I can electronically file my return. What do I need to do to fix this so that I can electronically file my return through Turbo Tax and get my $2,000+ refund?
