Is there a way to enter historical payroll if I'm already set up in QuickBooks?

Hi there kwc@telus.net,

it's vital that all your transactions be entered properly so that your books are up to date. QuickBooks Online is a great tool abe to help you calculate payroll for employees all while having those entries affect your accounting at the same time. I can point you in the right direction for assistance with prior payroll.

In order to find out the best way to enter prior payroll for your circumstances, I recommend reaching out to the Quickbooks Online support team outside of the Community. They'll be able to view your account with you in a secure setting in order to recommend the best way at getting that payroll information back in the system so that your payroll totals can be accurate. You can reach out to them using one of these methods:

Schedule a Callback or start a Chat: click (?)Help in the upper right > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat. 
Social Media: Facebook or Twitter.
