"Wanna" is short for "want to" which is the present tense of "to want". When talking about the past, we say "wanted". Also, whenever you use the phrase want + verb, you leave the verb in the infinitive (with "to" in front) For example: I want to see. They wanted to stop. I think I will want to go home.

I wanna wentted to go to the Jyujyutsukaisen museum . I wanted to go to the Jyujyutsukaisen museum.

I wanna wentgo to the Jyujyutsukaisen museum . I wanna go to the Jyujyutsukaisen museum .

I wanna wentted to go to the Jyujyutsukaisen museum . I wanted to go to the Jyujyutsukaisen museum .

Remember to use past tense for something that has already happened

I wanna wentt to go to the JyujyuJutsuk Kaisen museum . I want to go to the JuJutsu Kaisen museum .

Wanna and went are two different tenses. Wanna (English slang for want) is used in the present when you would like to do something. Went (past tense for want) is used when you already have gone to the place.

But,I wanted to go to the Jyujyutsukaisen museum, but I had to work overtime. I wanted to go to the Jyujyutsukaisen museum, but I had to work overtime.

This should be added to the end of the first sentence, with a comma.

But, I hadve to work overtime. But, I have to work overtime.

So, I will go to there this Saturday instead. I will go to there this Saturday instead.

You could just join all 3 sentences together with commas. If not, you shouldn't start a sentence with 'So'. You could add 'instead' at the end to make this clear as a separate sentence.

So, I will go to there this Saturday. So, I will go this Saturday.

This is technically correct, but I think removing the prepositions make it sound more native

So, I will go to there this Saturday. So, I will go there this Saturday.
