Filing Taxes

I used Turbo tax 2019 to file my taxes, however, it was always rejected.  I spoke to 2 different agents who worked with me and 3 times we filed and 3 times it was rejected.  I finally just gave up and filed manually, however, in filing my state tax manually, I was still charged 24.99 for the filing.  I still have no answer as to why my e filing was rejected.
