Yes, you can.

If your return doesn't have any income that you pay SE tax on (Schedule C), then you may delete it.

But first, go to line 57, Form 1040, to make sure there isn't an amount there.  To do that:

1.       Go to Tax Tools on the left-hand side.

2.       Go to Tools.

3.       Go to View Tax Summary.

4.       Click Preview my 1040 from the left-hand side.
