Can I report late 1099-DIV to IRS without a major penalty if the amount is very small (say approximate total of $300 for 2017 - 2021 period) I missed being shown in TOD?

You could Amend your returns for 2021 and 2020, but not farther back than that.

However, if a small amount reported each year does not change your tax outcome, you don't need to Amend.  Just keep the documentation for your records.

Here's more info on Do I Need to Amend?

If you amend, IRS will calculate any penalty and send you a bill.

if you missed a small 1099-DIV for long past years, don't amend.
