First thing you need to know is whether the amount of the 1099-K is included in the 1099-NEC. If it is, then disregard it. You can always just add up the income you had for a particular line of work, and just enter it in the self-employment income section, without entering various 1099's. As long as the income equals the amount of 1099's received (as long as your business income was all in the form of a 1099), you would be fine.
