I agree with @Bsch4477.
You can read about the various penalties at the IRS web site (link below).
https://www.irs.gov/payments/accuracy-related-penalty
Even if a penalty were imposed (accuracy-related), it would probably amount to around $12 (plus interest on that penalty and the balance due).
Essentially, it is up to you as to how you want to handle the issue at this point.
