Question on ordinary and qualified dividends on 1099-DIV

The 1099-DIV looks like this.  My question is: Is line 1b a subset of line 1a, or are they two different things?  Should I read this as I have $3413 in total dividends of which $613 are qualified, or should I read this that I have $3413 of ordinary and $613 of qualified for a total of $4026 in dividends?

 

The reason I ask is that when I entered line 1a TT showed me an estimated tax owed of $x, but when I put in the qualified amount it showed me an estimated tax owed of less than $x.deleteme.jpg
