Go back to the section 179 section and double check your entries.
Double check to be sure that it says you can take 100% and if so that you did not enter an amount higher than what you entered as the price.
If it does not say you can claim 100% then you will need to lower the amount you are claiming. Ex. If it says you can claim 50%, and you entered the asset as $50,000, be sure you only entered $25,000 as the amount to claim.
