Rejected

I have filed my boyfriend taxes 5 or 6 times online through tax act on the IRS website and it keeps getting rejected for some reason or another I fix it and they find something else with his return.  I then paid the 56.00 or whatever the price was to file it because of the medical coverage which he never used in 2023 or 2024.  Then they say his name is on someone taxes and they shouldn't be but won't give us information on who or where his name appears and now we're still out of money and no taxes yet and probably will get pentalize for this mess.  Can someone please call me or message me personally
