Hi,
I seen an old notice on my IRS account for a payment due. The due date of this payment was in 2021 but it was for the 2020 tax year. There was an initial payment in the 2020 tax year that I submitted but unfortunately it was unable to get fully processed. Since the payment for the 2020 tax year was unable to get fully processed, I got a follow up notice that accrued interest from that initial payment
I thought that the initial payment and accrued interest payment were consecutive payments, so I submitted payments for them separately as of September 2024.
However, I realized that the initial payment and the accrued interest on the notice are concurrent to each other.
Long story short, I didn't fully comprehend the notice as I should have and realized that the balance due in 2021 for the 2020 tax year was paid already before the due date of the notice. I got the years mixed up and payments confused, and overpaid too much.
I hope this helps.
