Yes, you can enter $5,000 as the amount that you forfeited. If you enter $5,000 on the screen that I showed you above, I think the credit will increase to $1,200, which is the maximum credit that you can get, 20% of $6,000. Go back and review your W-2 entries, and continue through the questions until you see that screen.
Alternatively, enter the $5,000 in forms mode on the W-2 worksheet, Part IV line 6.
