I sent 1099-misc instead of new 1099-nec for non-employee compensation. Will that be OK for 2021 tax return?

The IRS addresses this.

2021 General Instructions for Certain Information Returns Penalties Pages 19 and 20 states:

If you fail to file a correct information return by the due date and you cannot show reasonable cause, you may be subject to a penalty. The penalty applies:

• If you fail to file timely,
• If you fail to include all information required to be shown on a return, or 
• If you include incorrect information on a return.
