I did commented on your post.

Is this a correct sentence? As you know that we often make emphatic sentences by using "did"but when we make them we use 1st form but here 2nd form is used. I am just confused.

The sentence is erroneous. You should write:

I did comment on your post.

The emphatic auxiliary do already expresses the past tense: did. The verb connected to do should be in the bare infinitive form, as Rathony has said.

P.S. One possible source of confusion for the learner is that we can use commented after the auxiliary have:

I have commented on your post.

This sentence is in the Present Perfect tense, and here the use of commented is correct.
