IRS return acceptance code

How is the IRS telling you that you need an "acceptance code" from TurboTax?  Where are you getting that idea?  

IRS sent me a letter . 

What is the letter number or letter type?   What does the letter actually say?   Is it for your 2024 return or some other year?

Letter is Notice CP5071. Identity verification is required.  I got through that part and final step is to enter the IRS return acceptance code.  Turbo Tax did not provide this and neither did IRS, 

TurboTax does not issue any sort of "acceptance code".  Call the 800 number on the letter and ask the IRS what they want from you.
