1. Select a blank cell next to the data you want to sum, and enter this formula =IF(ISERROR(VLOOKUP(C2,$A$2:$A$7, 1, FALSE)),FALSE,TRUE ), then drag autofill handle down to apply this formula to the cells, if it displays TRUE, then the corresponding data exists in another column, and if it shows FALSE, the corresponding data is not in another column.

Note: in the formula, C2 is the first cell you want to check if exist in another column, A2:A7 is the criteria list, you can change them as you need.

2. Select the formula column and click Data > Filter to add Filter icon into the column, and click the icon to select TRUE from the Filter list. See screenshot:

3. Clock OK, now only the values which exist in another column are displayed. Copy them and paste to below location. See screenshot:

4. Then you can apply =SUM(D16:D20) to sum the values. See screenshot:

2. Then in the PivotTable Fields panel, please drag column you will sum based on into the ROWS field, and column you want to sum into the VALUES field. See screenshot:
