I have some checks that I need to put in but I need to go back to January 2019. It will only let me go back to June 2019. Does anyone know what I need to do? Thank you!

It's nice to have you here in the Community, @brian83.

It's my pleasure to give insights about your paycheck in your Quickbooks Online Payroll. 

The reason why you're unable to enter paychecks in your payroll account because the pay period is too late. What you can do is to create a prior payroll. This is to ensure accurate year-to-date(YTD) totals on your pay stubs going forward and correct the W-2 information of your employee. 

I suggest to contact our payroll support for them to enter for you as they have the tool proceed with the prior payroll in the protected surroundings. 

Here's how:

1. Click the Help button, then choose Contact Us.
2. Enter the concern in the description field, then hit Let's Talk. 
3. Choose either Start messaging or Get a callback. 
4. Complete the needed information, then tap Confirm my call or Send a message. 

Check out our support hours and contact us at a time convenient to you: Support hours and types. They are available Monday to Friday from 6:00 AM-6:00 PM.

Don't hesitate to leave a comment below if you have follow up questions. I'm always here to help. Take good care!

The limitation may be on importing transactions from your bank. There is nothing or should be nothing to prevent you from manually entering a check with a date of 1/1/2019 or even 1/1/1999 unless your books are closed as of 5/31/2019. Closing the books will prevent you from entering or editing data prior to the close date
