I'm using Self Employed and it's asking me who my "payer" is. I don't have a payer. I own a business with employees. Should I put my business as my "payer"?

Where are you in the program ?   Are you trying to enter a W-2 form for yourself from your own Sch C business ?

 

In the Sch C income section there are different screens ... you can skip the 1099-NEC section and simply enter the total income from all sources in the next section ...

 

To add to @Critter-3 's answer:

 

If you are a self-employed sole proprietor, you do not issue a 1099 or W2 to yourself.   You enter your sole proprietor business's income & expenses on Schedule C of your tax return.

If your business hires independent contractors or subcontractors and pays them $600 or more for the year, then you issue a 1099-NEC to them.  You enter those payments on Line 11 of your Schedule C.

If your business has employees, then you issue a W-2 to them and report their wages on Line 26 of your Schedule C.    Note that if you have employees, then you must obtain an EIN for your sole proprietorship.
