Find payment documents and payment amounts

I have 2 sheets, one sheet is generated by the software, the other sheet is the result (I need to install the formula for the input list file).
In the software sheet, column C is the VAT invoice number, column E is the number of documents created, column K is the total amount paid by the customer including VAT.
In the results sheet, I have the VAT invoice number in column B, column T is the number of documents created
I need to find the formula in column S and column U in the KQ sheet. Among Column U is equal to Sum from S4:S17 = 319,341,579, equal to cell J4 of the phan mem do ra sheet.
Meaning find the cells and combine them in the KQ sheet to match the payment from the phan mem do ra sheet?
Hope you can help
