Investors & landlords

The post from Sandyd5 is wrong.  You must report all your income no matter how small.  You must report all your interest that's $1 or more.  Even if the total of all your accounts is less than $10.

Enter it like you did get a 1099INT
Federal Taxes tab
Wages & Income
Choose Explore on my own or I'll choose what to work on  (if it comes up)

Put the interest amount in box 1
