Generally, you cannot amend a tax return from 5 years ago (e.g., a 2015 return filed in 2016, amended in 2020) to claim a refund, as the IRS (https://www.irs.gov/filing/file-an-amended-return) typically limits this to three years from the filing date. However, you can still file an amended return to correct errors (even if no refund is due) or if you are paying taxes owed.
Generally, to claim a refund, you must file an amended return within 3 years after the date you filed your original return or 2 years after the date you paid the tax, whichever is later.

The IRS 7-year rule primarily applies to keeping records for claiming a deduction for bad debts or losses from worthless securities, allowing a longer period to file for a credit or refund, but it's not a universal audit limit; it's often a recommended safe buffer for general record-keeping, with the standard IRS audit period usually being 3 years, extending to 6 years for substantial income omission (over 25%) or foreign income issues, and indefinitely for fraud.
The general amendment period for corporations and trusts is four years following the issuance date of the assessment notice. Nonetheless, the period is two years for corporations, partnerships, and trusts that meet the aforementioned definition of a small business entity.
There's no direct penalty for filing an amended return (Form 1040-X), but if your amendment shows you owe more tax, you'll face penalties and interest for late payment on that additional amount if not paid promptly, typically 0.5% per month (up to 25%) plus interest on the unpaid tax, starting from the original due date; filing the 1040-X quickly and paying any owed tax by the due date (or soon after) helps minimize these charges, as the IRS automatically adjusts for interest/penalties if you file and pay on time.
