You view/edit on screen the 1099 to be corrected and then there are a couple scenarios;
Say the should have gotten 1000 on the 1099 but they got 900, simple check the box for corrected and change the number in box 7 to 1000.
Say they shouldn’t have gotten a 1099 at all. You can’t just put zero’s in the box, the program won’t allow it, check the box for corrected and put -1 in box 7. This prints zero on the 1099.
Cannot file correction electronically unless you have more than 250 corrections for one client.
Print the corrected 1099 and the 1096 that goes with it and mail them in.
