I need help

[Tax payer13]

I got a letter CP 2000 from the IRS saying I owed $7530 for under-reporting my income last year. Turbo Tax said everything was ok with my return when I submitted it. I have tried to call turbo tax help and have been hung up on and I can't find anyone to talk to about my Turbotax filed 2021 tax return.
