Huh?  What do you mean by "timestamp" and what do you mean by "it" in this question?

Make a datetime field and when you INSERT the row, use NOW() as the value for that field.  Then don't change it ever again and it will remain as the datetime you created the row.  Don't use timestamp at all.

I have a table in MySQL database one field is known as timestamp. I'm trying to figure out which type to use where the row of data (it) only states the time is was created and not modified.

maybe you can use 2 datetime/timestamp fields, one for created time (which is can insert automatically when inserting row) and the second for modified time.

IIRC columns of the type TIMESTAMP may get updated automatically.  You might want to add a different column to the table to hold the creation DATETIME values.  Then you can have the creation DATETIME and the most recently updated DATETIME, too.

If the field name is timestamp, that won't hurt anything, but make the data type of that field   datetime, so you can set the value when you create the row and it won't change automatically.
