I accidentally categorized ALL my "transactions" to meals which completely changed every transaction, duh oops, can I get my data back as it is $40,000 in deductions?

We'll have to manually categorize the transactions again, jbolton44-twc-co.

You can do that by going to the Transactions tab. Let me guide you how:

1. Click the Transactions tab.
2. Filter the Type of transactions.
3. Select the dates.
4. Locate the transaction and then select a category under the CATEGORY AND TAGS column.

I've also added this article for more information in categorizing the transactions: Schedule C and expense categories in QuickBooks Self-Employed

I'm just a post-away if there's anything that I can help. Keep safe!
