I paid over $100 to TurboTax and submitted my return for 2023, but it looks like this wasn’t sent to the IRS. Where can I get in contact with someone without extra fees?

I submitted the return later in the year in 2023, but I paid for the Deluxe version of TurboTax so I could have the extra assistance. I remember filing the return, and I have the order information from then, but I need to know there my files went since the IRS has no record of the reports. They recently also filed a letter of no-filing, and I need to know how to fix this.
