I filed 2022 federal tax & I don't owe $. Today I got a letter from IRS CP503 saying I owed $2420.71. It doesn't give explanation why I owe this $. Any advice? Thanks

I checked my 2022 transcript and 
there were several lines with this $2270 amount.
-'Income Tax After Credits Per Computer' for $2270.
-'IMF Total Tax (reduced by IRAF) Per computer: $2270
-Total Tax Liability TP Figures per Computer : $2270 
Do you know what are those lines mean?  I did some research but still not able to understand why I'm being charged for $2227.  I'd appreciate any help and guidance in advance.  Thank you.

I RECEIVED A LETTER FROM THE IRS/STATE

TurboTax does not receive any information from the IRS or your state after your return was filed, so no one at TurboTax knows about a letter you received from the IRS or the state.
