So last night I largely completed my taxes but I have to file an extension due to an error on a 1099-R. Anyway, I paid an estimated federal amount due that was very close to the total I owed, entered that into the appropriate space which nearly zero'd out my federal owed, and logged out. I wrote down the amounts I had remaining for both federal and state. I just logged in a few minutes ago and to my amazement my federal owed jumped up over $1,700 and state jumped an additional $400. Just from logging in to the online version.
Really gives me a whole lot of confidence in this god-awful service after the mess with it saying it was going to file my return when filing an extension last night. I have no idea if my taxes are anywhere remotely close to correct now. Fix your sh*t Intuit. This will be the last year I use this service.
