Turbo Tax Online Self Employed

I am thinking of using turbo tax online self employed but wonder if it can handle at least a lot of dividend and interest income, capital gains, schedule C, K-1 income (thousands of entries) as I have two brokerage accounts.  I heard there is an option to print your return and mail it in with payment.  I have a Mac which is 10 years old and I cannot run turbo tax deluxe download for 2022 which I have right now.  Is the turbo tax online self employed an interview process? The advantage to the turbo tax online self employed is that I can get another couple of years out of my computer before system requirements catch up with it.  Reviews for the turbo tax online self employed appear to be good.  Any advice is welcome.  Thanks,
