Tell me where did you go?对吗,还是Tell me where you went?

Tell me where did you go?对吗,还是Tell me where you went?
Tell me where did you go?对吗,还是Tell me where you went?

Tell me where did you go?对吗,还是Tell me where you went?
这是个宾语从句,从句里的助动词did要省略,动词用原有的时态,即went.即宾语从句后用陈述句.
所以Tell me where you went?正确

两句都不好
语气委婉比较好：
Could you tell me where you went？

这应该是陈述句，第二句正确，改为句号

这是祈使句，直接说就好。tell me where you went

Tell me where you went，作陈述句
