First of all phrasal verbs are verbs, so, they can be conjugated in any tense. They have a past, a present, a future, a continuous, and a perfect form. So, don’t forget to use them correctly.
Next there are 2 different kind of phrasal verbs, 1 where you can separate the particle (preposition,..) from the verb, and others where you can’t.
Fill in: write some information on a paper or document.
As you can see here you can use both you can put ‘the forms’ between the verb and the particle or you can put it after. Both are good.
When you are using pronouns (it, they,….) you always need to put the pronoun between the verb and the particle.

Look into: investigate
You cannot say: I will
look it into.
Phrasal verbs which have 2 particles are always inseparable.
You can’t say:
I can’t put it up with anymore
