Good morning, adamsnate25, and thanks for joining us here in the Community.
It's my pleasure to help out so you're able to enter previous hand written checks for your employees.
These prior paychecks can be recorded by entering an additional pay date along with the amounts. In the Company payroll totals for this quarter page, select Add pay date for each individual paycheck date that occurred in the current quarter. Be sure to only enter the totals for each line item from that pay date. Your totals should be for all employees paid on that paycheck date.
I recommend checking out this detailed article that covers setting up a prior payroll.
You're welcome to comment below if you have any other questions. I'll be here to help.
