hytib: thanks for your response. Sorry this first experience with Turbo Tax was not good for you. I have used it every year since the late 1990s with no issue...but this was the first year I had to use form 2210 or needed to contact Turbo Tax for help. They don't seem to post any errata data on known issues once forms are released so their help line is clueless on anything other than user error issues. Since I likely overpaid taxes versus underpaid, I will just hurry up and wait until April and see if they fix it by then. If I see they fixed it, I will post a follow up.
