Why is it making me put in the same W2 twice

You should not enter the same W2 twice.  I would delete any W2 information that has been imported or entered in the return.

Then I would enter the correct W2 information manually.

It's easy to remove a W-2.

1. Open or continue your return.
2. Search for W-2 using the search in the upper right corner and then click the Jump to link in the search results.
3. This brings you to the Here's your W-2 info screen. Click the trash can icon next to the unwanted W-2 and then answer Yes on the following screen.

If you want to manually enter your W-2 info, we make it easy for you.

1. From Tax Home, open or continue your return.
2. In the upper right menu, select  and search for W-2.
3. Select the Jump to link at the top of the search results.
4. At the Let's start with some info from this W?2 screen, don’t enter your employer's EIN, just select Continue.
   1. Or, Add Another W-2 if you see the Here’s your W-2 info screen.
5. On the Let’s type in the rest of your W-2 info screen, you can manually enter your W-2 information.
