I already filed and received federal refund. Do I need to amend if I missed a 1099-MISC but still reported the income? Edits produce same refund.

I reported as rental income a check received from an outside entity for a tenant's rent. After filing, I received a 1099-MISC. Do I need to re-file to include the 1099? When I updated my federal return info to decrease the rent and add the 1099, it all came out exactly the same.
