Another method is go to the first 1099G and roll down to find 1=delete this year, 2=delete next year.

Enter a 1, then press Ctrl and the Down Arrow, Enter a 1, then press Ctrl and the Down Arrow, Enter a 1, then press Ctrl and the Down Arrow, Enter a 1, then press Ctrl and the Down Arrow, Enter a 1, then press Ctrl and the Down Arrow, Enter a 1, then press Ctrl and the Down Arrow, Enter a 1, then press Ctrl and the Down Arrow, etc. 

Notice I did not say Enter a 1 then press Enter.

Have Fun!
