It shouldn't affect your income tax return. No "1099-MISC" information is incorporated into your income tax return. All the IRS sees is a lump sum of "Revenue", (1099-MISC's to you plus and "general' income you entered), or a "Contract Labor" lump sum, (1099-MISC's you've prepared plus any other contract labor you entered where no 1099-MISC was required).
Keep working on sending your 1099-MISC's as you do want them in by the deadline.
