If you go to the FamilySearch 1950 U.S. Census Project page at https://www.familysearch.org/getinvolved/1950 you will see that four states have been completed and that only two more are open right now (as of the date of this post). Checking handwriting recognition from Ancestry.com is a different experience from indexing. The accuracy is significant, and it is apparent that the entire project will likely be completed in a matter of months and perhaps weeks.
It helps to read the instructions, here is a link to some Frequently Asked Questions. Here is yet another link with more information: https://www.familysearch.org/en/info/1950-census-details#updates. We have been checking on Facebook and following a lot of links, but the information is scattered around. Here is a link to the 1950 US Census group in the FamilySearch Communities: https://community.familysearch.org/en/categories/1950-us-census From this page there are a huge number of further links.Ancestry.com has a 1950 U.S. Census District Finder: https://www.ancestry.com/discoveryui-content/district-map/62308
All I can say, for more information, just keep clicking.
