我现在才意识自己错了? 英语该怎么翻译

i'm really wroing i get to know recently

Until now did I realize that I was wrong.

now i realized i had done something wrong.

I realized my mistake until now.
或
Until now I realized what I did wrong。
或
I realized I was wrong untill now.
或
Till now I realized I was wrong.
或
Until now I realized It's my fault。

I realize my mistake up till now.
关于did wrong。更加强调做错了。而不是错了。
关于i'm wrong 这是中国式英语。外国人从来不说i'm wrong。
关于 until的用法，
1.until 用持续动词。
2。not until 用瞬间动词
所以所有使用realize 并使用until的人，是完全的语法错误
以及，一般来说，英语所有的时间和地点都是放在句尾的。
将 till 或者是 until放在句首的人都是格式错误。

i did not realise what i was wrong untill now
