I eFiled my 1040 including my K1 info from a K1 I received. But I did not include the K1 form in the file sent to the IRS. Do I need to amend it to include the K1 form?

The K1 data - dividends, capital gain, etc. - info was included in the 1040 filing. I just forgot to send the actual K1 form itself. DO I need to amend?
