I would call 4 vs 11 "approximately the same" for all intents and purposes when the denominator is so huge especially when COVID deaths are much more generously assigned than flu deaths, per my sources, especially [4].

Not to mention, flu deaths are attenuated by flu shots, and pre-existing immunity. It's totally plausible that there are many more COVID cases than flu cases in that age group -- and of course those flu deaths will happen year after year while COVID is a very stable virus, and if you get it once, you probably won't get it again.

Certainly not enough data to conclude it's way out of line with the flu for this age group, in this season let alone if you factor in a few seasons end on end.

Lastly, with H1N1, the numbers are quite different, too.

The COVID-19 infection fatality rate in the 18-45 group is at least 0.11% in NYC. And that's assuming that everyone single person has been infected, that no-one else is going to die from now on and that the estimates are not going to be revised upwards because of under-reporting.

The infection fatality rate for seasonal flu [edit: in the slightly older 18-49 group] is around 0.2% considering symptomatic cases, and probably there are as many asymptomatic cases which give 0.1%.

So yes, it's not impossible for the infection fatality rate to be similar. With some strong assumptions including that it's five times as contagious. So yes, it's not impossible for the acumulated lethality over five years to be similar. And if you extend the period the common flu will be much more dangerous, specially as this young people became older.
