Yes - it will be difficult to get through to the IRS. I’m an Enrolled Agent and help people solve their IRS issues. I use a priority hotline as a Practioner and I too have trouble getting through.
Are you using TT online? Or desktop? If desktop you will be able to see all the worksheets and information and ‘probably’ be able to tell what happened. If TT online it will be more difficult since it limits the ability to see any worksheets.
I cannot say for sure, and in theory I agree the TT program should not have let that happen, but I suspect after having helped 1000s of people with their tax returns in the program (I used to work for TT) there may have been a box that wasn’t checked or some piece of info that was skipped over, causing the issue.
I can try and help you outside this forum if you’d like.
