ZCTA (level 860) total population in 2010 census

I am looking for 2010 census ZCTA total population data (table P1).  Do any of the summary files (SF1 SF2 etc) have this data.  When I parse  https://www2.census.gov/census_2010/04-Summary_File_1/Massachusetts/ma2010.sf1.zip    file in zip archive  mageo2010.sf1   folder: https://www2.census.gov/census_2010/04-Summary_File_1/Massachusetts/,  I don't get any 860 level data.  This agrees with the documentation:  https://www2.census.gov/programs-surveys/decennial/2010/technical-documentation/complete-tech-docs/summary-file/sf1.pdf .  There are other webpages on the Census website saying the ZCTA data is available for the 2010 Decennial Census.   Does anyone know download the data using a url ?

Thanks

Dave
