Singapore airlines is not a Sky Team partner. According to Schiphol's website, airlines that are not part of Skyteam use the following transfer desks: T3, T5 or T9.
According to the Schiphol map, transfer desk T3 is located in the Schengen area, so Singapore Airlines will not use that desk for flights to Singapore. T5 and T9 are in the international area, where T5 is in the E wing and desk T9 is located in the GH hall.
My research shows that Singapore Airlines flight 323 (AMS to SIN) departs from the G wing. As such, you will most likely have to use transfer desk T9, located here.
As for your specific question, you would probably not need the transfer desk. If you check in online and have your ticked printed then you can proceed straight to your gate. If you arrive from certain locations, you might need to pass the transfer security check first, but I do not know which specific origins that applies to. In any case, that would just be a check that you do not carry prohibited items on your person or in your carry-on.
