Hey there, @B-MUSIC-school. Thanks for providing an update.

During a conversion from QuickBooks Desktop to QuickBooks Online, it will bring over all accounts, regardless of status (if there are transactions associated with them).

That being said, if you make a register with transactions inactive, QuickBooks will create an adjustment entry to zero out that register’s balance. This adjustment might not look good on your reports. Be sure to talk to your accountant first. If you need an accountant, we'll help you find one near you.

Some types of accounts can't be made inactive. I've included those below for your reference. Please check that the account you're trying to inactivate isn't one of those listed below;

• Accounts used by a product or service: Make the product or service inactive first. Or change the account it uses.
• Income accounts that have un-invoiced charges: Make sure to invoice your customers for billable expenses, time, or charges first.
• Accounts that QuickBooks needs: Some accounts, like Undeposited Funds, can’t be made inactive because they serve important roles in your accounting. Learn more about these accounts.

Please let me know if there's anything else I can do to be of assistance.
