Form 1040: amortization of loan cost

[helenyin]

Which IRC section should I use? I want to amortize it for 20 years.

Asset entry worksheet, right click on the box for amortization codes and then enter the years below on the asset entry worksheet. Loan costs 446

Thank you.

I didn't find the exact place to do it. However, I scrolled down on the Asset Entry sheet and found the recovery period.

Go line by line on the asset entry worksheet, about half way down and you will see a check box to enter the correct amortization code, right click on the box and the codes will appear in a new window.
