Under 10 is ideal. If you have an RODI unit, it should be reading less than one. Did you let the water run for a while after changing everything? You should run several gallons through before testing.
At any rate, 19 to 20 isn't bad. It won't hurt anything in your tank, but an RODI unit should be performing better than that. If it's just an RO unit (with no DI), then that may be as low as it gets.

Measure the TDS of the water before the filter. You can then figure out what kind of rejection rate your getting. The filtered water should be at least 90-95% less than out of the tap.
