I like to file electronically. I like to file for free. I have an easy tax return. I am retired with only SS income and an IRA distribution. So, I go to the Turbo Tax File-For-Free thing. I fill out all the forms. I complete everything and go to file and Turbo Tax basically says "You cannot use the Free version, you must upgrade to the Deluxe Version" why? cuz my return includes Schedule 5. What is that? It's the form where you declare your 2018 pre-paid estimated taxes. Well, I don't work, I HAVE to estimate my tax liability. ok, I leave Turbo Tax. I go to TaxAct. I use their file-for-free software. I enter all the data. I go to file and they say "You must upgrade to the Deluxe Version because you use Schedule 5." Huh? ok, I go to H/R Block, use their file-for-free software. I enter all the data and hold my breath. H/R Block says "Congrats your tax return has been sent electronically". No cost. My return was accepted by both Fed and State. What am I missing? Where did I go wrong? I don't understand why I can file for free at H/R, but I can't at TurboTax and TaxAct.
