Reinstall TT TY2021 packages on new computer?

If I today buy from Amazon the TT Desktop packages (Home & Business for 1040 and Business for S-corp) and download to present computer will I be able to re-install on the new computer that I anticipate buying in January/February timeframe? 

 

I would like to get familiar with the software but am worried that TT won't let me download and install to more than 1 target device.
