What do you mean inputting your transactions?
Koinly tax
Oh you're gunna need this
You want an Xpub to import all your addresses that you've used.
Scroll to the end to see how to do so. I've never done this tho. So I'm not sure entering your private key somewhere is safe. But the Xpub is what you want for koinly.
