@hashu1 Yes, if the IRS catches the missing 1099-INT, your refund amount should be a little different & the IRS would send you a letter explaining what they did. If they send the refund without the 1099-INT correction then you would amend your return to include the form.
Missing the 1099-INT does not mean your return is flagged. Allot of taxpayers forget to add forms, that is why there is an amendment form.
The IRS is short hand right now due to Covid-19, it may take a little longer to process returns. You can keep checking the IRS Where's My Refund for updates on your return/refund. The Where's My Refund only updates once a day.
