Dear All,

I sent 4 1099-misc forms and along with 1 1096 form to IRS in March 2016. On 1096 form, I entered "4" in field 3 and "30000" in field 5 ($7500 nonemployee compensation for each contractor). However, the contractor A told me that he have provided me an incorrect SS#. So i have to submit the corrected 1099 and 1096. According to the research, I should submit two separate sets of forms, but I'm still confused about the reporting procedure. Here is my understanding:
1st set of the forms: 1 1099-misc form (check "CORRECTED" at top of the form) which shown payer's and only contractor A's information (the incorrect SS#) and 0 for money amounts (don't need to include other 3 contractors); for 1096 form, i should enter "1" in filed 3 and "7500" in field 5. Does anyone know whether this is right.
2nd set of the form: 1 1099-misc form (don't check "CORRECTED") which show contractor A's correct SS# and $7500, should I include the other 3 contractors' 1099 and not? for 1096 form, should I input "1" in field 3 and "7500" in field 5, or input "4" in field 3 and "30000" in field 5?
Only one contractor's SS# is incorrect, but I'm not sure if I should include the other 3 contractors' information in the amended 1096 and 1099 form.
Also, for copy B to recipient, should I give contractor A two 1099-misc forms: one is check "CORRECTED" but incorrect SS# with $0 dollar amount, and another is no check "CORRECTED" but with correct SS# and $7500? If not, how should I provide the amended 1099 to contractor A?
The last questions is can I mail two sets of the 1099-misc and 1096 form together to IRS?

Thank you so much for your kind help. Really appreciate!
