It has to come from somewhere. It can come from owners, workers, or consumers. If it came from consumers (higher price or lower quality for products and services) this would affect the competitiveness in a straightforward way. [1] and [2] claim that it instead comes from owners and workers, with considerable uncertainty about the ratio between those. If it comes from owners, it increases the corporation's cost of capital – but only to the extent that investment is global. If it comes from workers, it decreases the ability for the corporation to compete for labor – but only to the extent that labor is global. So you're correct that it does not affect competitiveness in a sufficiently non-global economy.
It is collected from owners. Tax collection and tax incidence are separate issues. In economics parlance, where tax "comes from" or "falls on" refers to tax incidence, not tax collection.
Tax collection and tax incidence are indeed separate issues.
The tax incidence falls on owners - probably at least until profit taxes reach ~80% or capital became magically very scarce for some reason that clearly doesn't apply to the present day.
