The form 1099-NEC for the tax year 2021 has changed slightly. According to Sage:
1099 NEC form will print data only on the official Copy A form (Red 3/page forms) that have the pre-preprinted background for the year 2021.
The State, Payer, and Recipient copies will print data and background on the 4/page (4-up) blank form.
Sage offers a variety of forms via their online store here. You may also be able to pick up forms from local office supply stores though you should do so early in the filing season since most forms are sold out when gone.
Please consult with your tax advisor on the proper filing requirements for your specific situation.
