IRS online account has a balance due even though payment was made in full on 4/12

Hi guys,

I need your help! So I filed the federal tax return with TurboTax for 2021 tax year on 4/10. For some odd reason I was not prompted by TurboTax to pay tax due with the e-filing. 
Based on the turbo tax payment instructions I later printed out, they wanted me to mail a check to IRS. But instead of mailing a check I went online and paid the tax due fully on 4/12 by bank draft and the payment was successfully processed. 

However, today, after months of processing, my IRS online account is showing a balance due, which is a sum of the original tax due (per turbo tax 1040 return )+ penalty and interest!

I then downloaded  the account transcript and realized the full payment I made on 4/12 was not reflected in the account activities at all. How can they post a balance without calculating  my payment first and not only that, also charged me interest and penalty? The payment was made 2 months ago and they clearly have received.
The IRS account online has a separate payment activity page,and  my payment is being listed there. It seems that my payment was not been reconciled with the tax due or something like that? It’s like they took my payment but did not apply it to my taxes.  Is that a miss on the IRS? What should I do?
