You have to either type the lyrics in by hand(uggggh), which I never do, or download them from the internet.
Here's a great lyrics search engine to help you.

If they don't have what you want there are others out there. Another technique is to type a few less common words of a line from the song in quotes and search the internet. For example if looking for I Will Always Love You, you might type in "I'll think of you every step of the way"
If you have a word processor like Word Perfect, you can copy and paste there first, convert to all caps if you wish to use all caps, and save bookoos of work.
Hope this helps,
