If you erased your Farm Bureau W-2, just go back into the W-2 interview and enter it again. Enter "w-2" in the Search window and select "jump to w2" from the results.
If you have a Morgan Stanley W-2 and want to delete it, then see: How do I delete forms in TurboTax Online? Find the Morgan Stanley W-2 (or 1099, if that is what you have) and delete it.
You can also delete any unwanted W-2s from the W-2 interview screens. Select the "trashcan" icon next to the unwanted W-2.
