Answer:
It is all correct, except "¿Llenaste el formulario?" it should be Rellenaste (you) :Fill in. Instead of Llenaste. (I am a native Spanish speaker)
Step-by-step explanation:
Rellenar (infinitive) is to fill in a paper. The declension is Rellenaste (you)
Llenar (infinitive) is to fill-up a container. The declension is Llenaste (you)
Hope it helps you! :)
