The finale of Timeless aired the next winter and was titled "The Miracle of Christmas Parts 1/II":

I wonder if it just hasn't been added to Netflix yet, for some reason? sigh I miss Timeless ...

There is more time travel later on in the Outlander TV series (and I assume in the books), but it doesn't start until later on--and meanwhile there sure is a lot of romance and plenty of fighting, and they don't go short on the drinking! Overall the series is about a 20th Century woman trying to adapt to a very different past, but her romantic life is a large part of the tale. It's just that her love life is complicated not just by two men, but by one of them being her husband who hasn't even been born yet! I like both history and time travel confusion, so it's the thing for me.
