When you create a time-series gage you must select a time window. You should see a "+" sign next to each time-series gage. Click the "+" sign to see all time windows created for the gage. By default there is 1, 01jan2000, 00:00 - 02jan2000, 00:00. When you select a time-window in the watershed explorer, you will see 4-tabs in the component editor, time-series gage, time window, table, and graph. You should be able to enter the time-series data on the Table tab.

You cannot define an elevation for a precipitation gage. Only temperature gages need an elevation (really only if they are used in the temperature index snow melt model).
