Baltimore City

I live in Baltimore City and am trying to efile my returns.  

 

On the Information Worksheet under Locality Information it says "Maryland county (Baltimore City residents leave blank.)"  I live in Baltimore City but it will not let me leave the filed blank, Baltimore CIty is not a choice in the drop-down list, and I cannot proceed.  

 

Also, the instructions say "... select your County or, if applicable, 'Baltimore City'".  Again, Baltimore City is not a choice and filling in Baltimore City is not what the instructions say,
