Copy list of data from one table to another table

Hi, I need to create a checklist for different activities with “Activity Name”, “Status”, “Images”, “Remarks” which are stored in the database table already with the name UNIVERSAL CHECKLIST TEMPLATES . so I am retrieving the data from the database in RG group and filtering the group by “Taskname”

To store the checklist data I created a table CHECKLIST DB with same fields and data types

so I am trying to create checklist for every task . when I create checklist, activities should select from database which are filtered by taskname and create new record in CHECKLIST DB table, but I stucked at creating new records in CHECKLIST DB.

please help me how to create new record and copy data from one table to another table. Finally I want a user should able to create checklist and user should able to submit the checklist …
