I uploaded cvs file and all calculations are wrong

I'll help with your banking transactions, walterfar-yahoo-.

Do you mean the amounts are incorrect after importing the transactions? You can delete the file and import the transactions once again. This is to check if an incorrect file was imported. Here's how:

1. Go to the Gear icon and select Imports.
2. Click the Import older transactions under the Action column.
3. Under the Files imported section, look for the file that was imported. Then, click the Delete icon.
4. Click Delete.

Once done, re-import your CSV file and check if the amounts are already correct. If they are, you can now proceed to assigning categories to them. Here's an article as a guide: Categorize Transactions In QuickBooks Self-Employed.
