In 2010, the sum of the year's digits is 3. What is the first year after 2010 in which the sum of the digits is 3, and the year is odd?

It's not possible... 

 

if the year is odd, then it must end in a 1, 3, 5, 7, or 9.

 

But, recall that we already have a 2 as the leading digit, so the only way it will work is if it's 2001, but that before 2010, not after 2010.

The year 20,001 will work, unless you consider it to be so far in the future that it's out of contention.
