Get your taxes done using TurboTax

for the 2017 year, that happened to me as well.

I did not know it until the IRS came asking for a bunch of money.

Went through nearly a year of hell working with TaxAudit service (best advice - spend the $45 and sign up for it - well worth it) and reduced my fees, but I still ended up having to pay a fairly large chunk of change. Was not fun.
