Unfortunately, there is not an exact dollar amount for what is too low of an error that you will need to correct.  However, as Cynthiad66 stated, for an amount as low as $12, the IRS will likely not pursue an audit because it would cost them more to pursue the audit than it would cost to dismiss the change.  

You can still file an amended return for the 2020 return electronically.  Any return older than 2020 can be amended, but it needs to be filed by mail.
