Lacerte is not really designed for entering data straight off of forms. It's up to the preparer to figure out where on the return they'd like the income to go, and entering the amount, after any appropriate adjustments, into the relevant screens.

If you have state withholding from states that require the 1099 be replicated, the input for 1099-NEC is in the same place it was for 1099-MISC: Screen 14.1 under Tax Withheld.
