I wonder is that correct:
I was used to doing = I used to do = means in the past and you are no longer doing
and
I am used to doing = I get/got used to do = means you are still used or accustomed to doing it
?

Examples:

He used to cycle to his work.
I was used to typing fast.
I am used to drinking coffee every morning.
She got used to the cold climate.
I'm gradually getting used to it.

Вот, например, https://www.macmillandictionary.com/dictionary/british/used-to_1
Don’t confuse
▪ I am used to doing something
▪ I used to do something
If you are used to doing something, it is familiar to you because you have often done it before. Use the -ing form of the verb in this pattern, not the infinitive:
✗ Looking through the newspapers every day, we are used to read terrifying reports about crimes.
✓ Looking through the newspapers every day, we are used to reading terrifying reports about crimes.
You can also say that you get used to doing something:
Children soon get used to spending much of their free time watching TV.
If you say that you used to do something, you are talking about an activity or habit in the past which has now finished.
I used to play squash reasonably well.
This means that the speaker no longer plays squash well

И на самом деле также не понимаю раличие между
I get used to doing
I got used to doing

*Я к сожалению не понял различие между
I am used to doing
I was used to doing *
возможно, у вас случилась путаница в голове, потому что вы пытаетесь разобраться "через перевод". а тут тот случай, когда по-русски мы не всегда делаем разницу. тут лучше переводить дословно и/или включать лёгику:
I am used to doing - я (сейчас) есть привыкший - у меня (сейчас) есть такая привычка/обыкновение, для меня (сейчас) это нормально и совсем не странно.
I was used to doing - все то же самое, только в прошлом.
