how do i send a 1099

Please be more specific about what you are trying to do.    There are almost two dozen kinds of 1099's.   What kind are you asking about?  Are you trying to create one to provide to someone else?  Trying to enter one into your tax return?  

You can prepare W2 and 1099NEC, MISC, INT & DIV  in either the Desktop Home & Business program or the Online Premium version using the QEF Quick Employer Forms.
