lendle is Kindle only, right?

to return a Kindle loan (whether from an individual, or the new library loaning program), you go to amazon.com, go to Manage My Kindle, and find the book there.  there will be a pulldown menu to the right of each book, and one of the options for a borrowed book is to return it.  click that, and shortly the book will be returned, and you'll get an email notifying you of it's done.

also, when the loan expires after 14 days, it'll automatically return itself if you haven't already returned it.

Amazon and the book owner will know you returned it, but it won't show up as returned on Lendle. Their FAQ says...

I’ve returned a book to the owner, but Lendle still says I’m borrowing it. Why?

Because Lendle can’t know exactly when the book is returned, we assume all lends take the maximum 21-day period (seven days to accept the book and 14 to read it). On the 22nd day after the book was loaned to you, the status of the borrow on Lendle will change to “completed.” Note that this does not affect your borrowing status. If you have borrow requests, you may use them, even while Lendle has you “borrowing” another book.

So you'll just have to wait for it to time out on your "Your Requests" page.

Ok, thanks for the help!!
