Can I change QB online to print 1099-NEC forms 3 to a page as required by the IRS instead of 2 to a page?

I can help you with printing the 1099-NEC form, @useraliciastevens3.

QuickBooks Online can print 1099-NEC forms 3 to a page. If you're not able to print your 1099 forms correctly, this can be caused by your browser. Intuit recommends using Google Chrome or Mozilla Firefox. If printing still doesn't work on these recommended browsers, I suggest going to this Print your 1099 and 1096 forms article and proceeding to the Have problems printing? section to follow the steps based on the browser you use.

Here's an article that explains the steps you need to take if you have to file both a 1099-MISC and a 1099-NEC. It provides information on what you should do before e-filing both forms, such as having a separate expense account for each form. Additionally, it explains how to set up QuickBooks to ensure that your 1099-MISC and 1099-NEC forms are filed correctly: Modify your chart of accounts for your 1099-MISC and 1099-NEC filing. 

Refer to this article on how to correct errors or make amendments to 1099-NEC or 1099-MISC forms after they have been e-filed. It suggests different solutions depending on whether the forms have already been filed or are still in the process of being created: Correct or change 1099s in QuickBooks.
