If we have vs. if we have had?

Hi; first of, I'm sorry, I don't know how to name these two examples grammatically correctly, so let me explain.

I have hard time making difference (only with the usage of "if") between the meaning & usage of the following two examples:
A> If we eliminated (...)
B> If we have eliminated (...)

Would you, please, explain this to me?

Thank you a lot.~

B. Not a hypothetical conditional: The if-clause is a past / completed action Let's wait and see if we have eliminated all of the problems. A: Conditional; If (condition), then consequence (using would ).

  • B.
  • Not a hypothetical conditional: The if-clause is a past / completed action Let's wait and see if we have eliminated all of the problems.
  • A: Conditional; If (condition), then consequence (using would ).
  • This is present tense, conjecture: If we eliminated all the problems, we would get a bonus.

The present, present perfect, and future of the present (with will) go together.
The past, past perfect, and future of the past (with would) go to
