yes you can amend your return. you don't need any corrected forms from Schwab. That 1099-R is correct because there was no direct rollover.
since it was an indirect rollover, you'll need to do is go back to that IRA section and go through the pages until you reach the page that says "what did you do with the money from XXX?
then check the box you "moved the money to another qualified retirement account (or returned it to the same account)"
also check the box that says you rolled over all the money
if necessary, delete form 5329
your 1040 line 4b should be zero for this withdrawal and the word rollover should appear
