Unable to put two lines in one cell - have tried control+option+return AND control+command+return

Nothing seems to work. Went to tech support, they couldn't help and told me to come here. Excel is updated, MacBook Pro is updated, have logged on and off, closed application on and off, etc. Any suggestions?

@cgmetcal I guess you mean to insert a linefeed inside a cell as shown in the picture below.

In the example, I typed:

Row 1 <alt-Enter> Row 2

Make sure that the cell is then formatted to Wrap Text.
