Never in our lifetime have the purposefully shut down most of the economy and then later on cranked it back up. That fact alone caused all of the data to be grossly exaggerated, both to the downside and upside. So you have to take that with a grain of salt.
In the recessions of 2000 and 2008, GDP declined and eventually recovered but it was due to a natural recession. This one was a manufactured one. Hope that helps to explain it. While I’d love to give Trump credit for the upside numbers, it was the drastic downside numbers (due to the shutdown) that made way for the drastic upside, upon reopening of the economy. You can see it all easiest on this chart.
