Tax declaration 2023 received but never accepted. What I should do?

Hi there!

My 2023 tax declaration filled by turbotax electronically was received but never accepted so I never got the return.

I let the year run, busy with different stuff until I realized never got the return.

Never got an irs letter and, honestly, don't have the time to hang on the phone for 2 hs.

What I should do? maybe the tax fell between bureaucracy?
