I'll share information about logging back into QuickBooks Online, @jkassis97355
When you log out or get logged out due to inactivity, QuickBooks doesn't have the option to go back to where you left off. You can do that if you have the link to the last page before logging out. Then paste the link to your browser so you will be routed to the last page when you log in.
Also, feel free to browse this link here if you need help with other tasks in QBO. It has topics with articles that'll help you through the process. Just look for responses that suit your concern.
Let me know if you have additional assistance with navigating QuickBooks Online. I'm always here to help. Have a great day.
