Transactions showing in history but not being able to record

Corrupted data can cause this unexpected behavior, DR619. 

Let's run the Verify/Rebuild utility to detect the data damage. Here's how:

1. Click File.
2. Go to Utilities, then choose Verify Data.
3. If QuickBooks detected no problems, there's no further action needed. If you receive a message, "Your data has lost integrity," the file is damaged. Just continue to Rebuild Data to correct the problem.
4. When you Rebuild Data, you'll receive a message to back up your company file, click OK. The utility starts as soon as the back up is finished.
5. Click OK when you get the message "Rebuild has completed."
6. Run Verify Data again to check for remaining data damage.

If you're still unable to view the transactions, you can use the QuickBooks File Doctor to fix your company file.

Once done, recheck the transactions so you can apply the payments.
