I have been playing with scripts to try and figure out this tedious task as there are 600ish rows in my sheet, times 4 sheets.

So far I have come up with this

function myFunction() {
  var ss =SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();

  var lr = ss.getLastRow()
  var lc = ss.getLastColumn()
  var fillDownRange = ss.getRange(2, 1, lr, lc)


However, this copies it everywhere... I am looking to find a way to copy it every even row (2,4,6,8...) Any suggestion would be appreciated.

This better might give you a better visual. I am trying to put the formula in those blank spaces.

Have you made a start on this? I don't know Apps Script, but cobbled together the following.

If you copyTo all rows, they will naturally be overwritten. I'd suggest stepping through the even rows instead.

First there's a problem with that approach; if not using the "intelligent" formula copying, the formula's A2 reference will not update, so rewrite the formula to refer to "the cell above the current cell", e.g. instead of
use something like

Then, instead of overwriting everything, step through the rows in pairs—increment by two. E.g.:

function overwriteEvenRows() {
  var fillFormula = "=IFERROR(VLOOKUP(INDIRECT(\"R\"&ROW()-1&\"C\"&COLUMN(),FALSE),Responses!$M:$N,2,false))";
  var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var lr = ss.getLastRow();
  var lc = ss.getLastColumn();

  var thisRow;
  for (thisRow=2; thisRow<=lr+1; thisRow+=2) {
    ss.getRange(thisRow, 1, 1, lc).setFormula(fillFormula);

I don't know what the odd-numbered rows' values mean or what your Responses sheet looks like, but I made a demo sheet with filler values if you or others want a starting place to experiment.
