Yes, you can get back everything by just turning off the QB Commerce. Please take note that once you turn off the QuickBooks Commerce, you'll not be able to access the features coming from it.

Afterward, make sure to turn on inventory tracking in QuickBooks Online. Here's how:

1. Go to the Gear icon.
2. Select Account and settings under Your Company.
3. In the Sales tab, select Edit ✎ in the Products and services section.
4. Turn on Show Product/Service column on sales forms.
   You can also turn on price rules if you want to set up flexible pricing for the things you sell.
5. Turn on both Track quantity and price/rate and Track inventory quantity on hand.
6. Select Save. Then, Done to reflect the changes.
