CBS unveiled their fall schedule today, TAR32 is scheduled to air Wednesdays at 9 this fall. Deadline is keen to note that TAR is the ONLY show on CBS's fall schedule that has actually filmed. The rest of their schedule is business as usual, with the hopes that Hollywood will be able to restart in the summer.
As for TAR33, CBS did make some comments about it in this article: https://deadline.com/2020/05/cbs-navigates-tricky-international-waters-with-the-amazing-race-survivor-1202938568/
The highlights: “In terms of Survivor and The Amazing Race, we’ll get those into production as soon as we can safely get back into production. That’s going to be a little more complicated because we literally have to navigate some international waters,” CBS Entertainment President Kelly Kahl told Deadline.
“If we get back into production [on The Amazing Race], you can trust that we have plotted out all of the safe and smart ways of doing it. Some countries are more affected than others and these producers are some of the best in the business and they will plot out a race that sticks to countries that are safe,” added Kahl.
The cynic could note that he says "IF we get back into production on TAR", rather than WHEN, but it does seem like they are committed to completing it, if they can do it safely.
