You can type in "dar" in the conjugation tool (blue toolbar at the top of the SD page) and it will give you all the tenses of any verb.
It should be "tú diste" - no S. Us native speakers always do that because most tú forms end in 's' - but not in the preterite!
I really think you'll learn more by utilizing the Conjugate tool instead of us giving you the answer. Just click that link and you'll see what I mean.
