The answer is it depends. Did you voided check from the prior fiscal period? Or are we talking about a check that was voided and dated in the current fiscal period? If it’s the latter, you can go in and edit that check, put the amount back in, and backspace the word void out of it. Then go to the register and find the check and un-click the R stands for reconcile. Now that check will appear to be able to be selected when you reconcile in the amount will be reinstated.
I hope that helps, if not ask more questions. Have a great Sunday.
