I'm not an economist, so tell me where I'm wrong here.
But there are 2 important ideas in supply. The actual production and the capacity. The capacity is the theoretical amount that an economy could produce of a particular product.
During covid we've seen a huge reduction in demand in several products that created deflation in a lot of markets (eg oil).
The opposite is also true. (eg lumber)
The problem comes when demand feels stuck being low, then that drives production down, and also near-term capacity down as well.....
It's good that you are not an economist, because that means you might use logic to look at the topic ;)
Lumber was extremely deflationary - especially since the last very dry years (here in Europe) have lead to over-production. Lumber was put in huge storages that were rained on constantly. That is (relativly) expensive and destroys a bit of the lumber, bit keeps it fresh until someone buys it. Thats how low the prices were in 2020.
The prices however spiked up when the economy got back on the wheels but is going down again. There is a lot of complicated Covid stuff going on.
Not very complicated however is that with the sudden electric car boom the prices for lithium and chips has skyrocket in this year, because both are things where production is not only very concentrated in very few production points, but also takes years to increase.
THAT is what drives prices up: More demand than production capacity.
If however we are talking about "business grade toilet paper" - the stuff only companies buy - then prices won't go up however much money you print (if we aren't talking about insane amounts) because even with a lot more money, there is simply no one buying it.
Or in short, as long as capacity is not (nearly) fully reached, money printing will not result in inflation, the companies will simply increase supply when demand is close to max. production and they thing it will increase.
That is Modern Monetary Theory in a nutshell.
Of course at the moment with Covid, the "Eco-Boom" and transport cost problems, there is a lot of insecurity, which is the reason that nobody can really predict what will happen. Another Suez-Canal blockade for a few weeks or even month will drive up at least some prices (esp. here in Europe) up a lot. A new Covid-wave with a deadlier varient may result in a deflation caused by shutdowns etc.
