I am behind with my bookkeeping. I need to post several months will quick books allow me to enter all deposits at one time for one month and then all expenses?

I can help you with adding your deposits and expenses to your account, @maddiematt.

You can enter multiple bank deposits and expenses at once. Please take note that you can only enter one type of transaction at a time, either bank deposits or expenses, but not both. Also, this feature is available if you're subscribed to QuickBooks Online Advanced. 

Here's how:

1. Go to the + New button and click on Batch transactions. 
2. In the Select transaction type ▼ drop-down, select Bank deposits or Expenses. 
3. Enter info into the fields. These are the same fields you see on a regular form in a flat view.
4. You can now provide all the necessary information.
5. Click on Save once you’re done. 

You can check this article for more information: Create multiple bills or expenses in QuickBooks Online Advanced. 

Also, you can check these articles for more information on how to record and make bank deposits and on how to enter, edit, or delete expenses in QuickBooks Online. 

Let me know if there's anything that I can assist with adding and managing your transactions. I'm always glad to help in any way I can. Have a wonderful day!
