Expenses from my credit cards are not download to QB

Let me guide you on how you can download your credit card transactions, Olu1.

May I know what's the name of your back? QuickBooks Online (QBO) downloads transactions every night automatically. You'll want to manually update your bank to refresh the connection. Here's how:
 

1. Go to Bookkeeping, select Transactions, then select Bank transactions (Take me there).
2. Select Update.
3. If asked, enter your Multi-Factor Authentication (MFA). Then select Continue update.

This updates all your connected bank and credit card accounts.

However, if your credit card transactions aren't downloading, you can sign in to your bank's website to check. You'll have to make sure to get the URL QuickBooks uses to connect. I've provided the steps below:

1. Go to Bookkeeping, select Transactions, then select Bank transactions (Take me there).
2. Select Link account. Note: You won’t add an account, you just need the listed URL.
3. Search for your bank and select it.
4. Copy the URL listed for your bank.
5. Sign in to your bank or credit card's website using the copied URL.

Use MT Online or one of the converter tools (e.g csv2qbo) as a workaround.
