Hi xHealthY
I assume your teacher has probably told you that one basic format for this sort of thing is "
have something done". You can look at that as a "base" form. When you use this format, you are basically saying that a Person A causes an unidentified Person B to do something. In other words, A has something done (by B). Let's look at your first example:
-
Someone does my taxes every April. (B does my taxes every April.) The verb "do" is used in the simple present.
The only way that "someone" would do your taxes for you would be if you asked or told "someone" to do that. Therefore, you cause "someone" to do your taxes for you. "Someone" is non-specific Person B, and you are Person A in this case.
-
I have my taxes done every April. = A causes B to do A's taxes every April. The verb "have" is used in the simple present.
Now let's look at question 1:
1. Someone is repairing my computer. The verb "repair" is used in the present continuous in that sentence, so you need to continue with that tense in the "have something done" version of the sentence. In other words, you need to use "have" in the present continuous form":
1a. I
am having my computer
repaired.

2. My favorite mechanic at Majestic Motors checked my car.Your second sentence is different from sentence 1 because in this case you are
not referring to a non-specific "someone". In this case the person who is doing the work is specified.
The usual format for this would be "
have someone do something". Did your teacher also mention this format to you?
