score

I'm trying to input a piano part, (I am not a musician) which has a time signature of 4:4 and the stave has 3 Crotchets vertically, then 3 Quavers starting below E, F & A.
A further 3 quavers D, F & E but with another row below, starting in F, A & D.
However there are another 3+3 quavers D, F & E but with another row below, starting in F, A & D.

I have tried changing the time signature of the measure/bar with no effect.
How is this achieved?
