I'd recommend asking your Guild Leadership, check the official Wiki, check the fan Wikia, ask in game support, Google "Forge of Empire How do I donate to Guild Treasury", use this Forum's search function.
I guess you did the last, but next time look for a thread from the last year .
But I guess necromancing a 5 year old thread that couldn't answer anything close to your question works too.
If you are absolutely sure you donated the right Goods, file an ingame support ticket.
If the preceding 2 posts didn't answer your question, more info please.
PC or Mobile?
Part of a DC or a Quest? Can you post a screenshot of the request? If you can't post a screenshot and it is a Quest what is the name of the Quest? If it's a DC can you quote the exact text of the DC?
Next time though, if you do run into something that you don't understand in game, start by asking your Guild Leadership.
Good luck.
