I forgot to file my 1099-INT on my 2017 taxes of $71.05, and my return had been accepted and is processing. Do I need to amend this? If so when?

Yes, you have to amend your tax return.

You usually have three years from the date you filed your original tax return to file Form 1040X to claim a refund. You can file it within two years from the date you paid the tax if that date is later.

If you are due a refund from your original return, wait to get that refund before filing Form 1040X to claim an additional refund. Amended returns take up to 16 weeks to process. You may spend your original refund while you wait for any additional refund.

If you owe more tax, file your Form 1040X and pay the tax as soon as you can. This will stop added interest and penalties.
