Where do I enter interest income if there is no federal slip for it?

On the T1 Worksheet for line 12100 I cannot enter any data in the "not reported on any information slip" field

I found the answer. You have to be VERY CAREFUL when you click in box 4 of line 12100.  It only senses it if you click in the bottom of the box. I also was able to enter it in box 7 of line 12100.
