Don't know what "TLP" is, but here's how you buy Acrobat 2020:
Go to the Adobe Products Page (https://www.adobe.com/products/catalog/software.html) and sort the products by name by clicking the "A-Z" button on the right. At the top of the list you'll now see Acrobat Pro 2020. Click on the Buy button next to it. If you have a prior qualifying version change the "Type" drop-down to "License Upgrade". Otherwise leave it as "Full License". Then select the other options (OS, Language, etc.) and complete the purchase. You'll get a full license, not a time-based subscription.
