Filed my 2021 tax returns with Form 14039 on Apr22. Paid all the federal dues through IRS online. But still my return has not been processed. Can somebody help?

Online tax filing agency told me that they couldn't file my returns electronically due to someone has already submitted. So they asked my to submit 14039 form with my returns manually sent to IRS. I did that submitted on 04/22/22 but still its not processed.
