I'm not able to type something in a certain box. They already put the amount in for me.

No one else can see your screen or your tax return.   What "box" are you having trouble with?

So that we can better assist you, can you please provide specific details about the issue you are experiencing? Where in the program are you not able to enter your information?

When they ask for how much I made in Indiana they show the total of the two W2s I received, but the box to type it in is automatically filled with only the amount of one W2. When I try to select the box nothing happens and when I hold down on it there are no options for cut, paste, or copy.

You cannot cut and paste data in for a W-2.   Type it in by hand.
