What about "I got it" in English" which means like "I will do it myself (you don't have to do it.)"

For example:
When you want to open the door or keep something that felt down, you say "I got it"

Then, your friend don't have to open the door or keep that thing because you will do it yourself.

I wonder why they use past tense when It will happen in the future.
