Chase bank sent me 1099-MISC for $50 signup bonus when I opened a new account in 2019. I forgot to add this form while doing my taxes. This link says 1099-MISC should have at least $600. Since it is just $50, do I need to amend my 2019 federal and state tax returns?
PS: My tax returns (federal+state) were filed and accepted and I got my tax refund amount back. I haven't received any notice from IRS or state tax agency regarding this.
