Update corresponding cells on master sheet when data entered to filtered sheet

Hi I am new to VBA and have a limited understanding of it’s workings.
I want filter results from a master sheet onto separate sheets (achieved).
The results on the filtered sheets have data that needs to be added to the row. So if I updated the filtered sheet , row C cell 2, then the master sheets corresponding row in column E will update the same line of information.
Does that makes sense?
The filtered data changes often, each time the macro is run (due to other parts of the master sheet being changed). The data I entered on the filtered results needs to be saved on the master sheet and when the filtered results change column C on the filtered sheet need to correspond with the master. So blank if it’s column E cell is blank or show whatever data is already there (not too important that part)
Any help would be much appreciated. I have tried a number of things though I think I would confuse things if I quoted what I have tried as I am not a very competent user. Thanks.
