Get your taxes done using TurboTax
yes online has different pricing tiers for different schedules, it can be more expensive than desktop and you can only do 1 return per account. also as you may be aware by now the workflow is different, there is no forms mode.
there was an offer 2025 if you bought the desktop version, to be able to upgrade to online premium for Fed and State at no extra cost, see article & screenshot below.
no one here can resolve a billing issue tho, you'd need to call Turbotax support and see whether you can switch to this other offer or get a refund for online in these circumstances (say "billing" when you call I think). Otherwise I think they regard the 'online' product purchased thru a retailer as non-refundable, see here.
