Get your taxes done using TurboTax

But in this answer from link below it is stated the opposite  information regarding your "note":
https://ttlc.intuit.com/community/taxes/discussion/how-do-i-know-if-my-installment-payment-plan-was-...
"If Form 9465- Installment Agreement Request was filed with your return and your return was accepted, you can consider the payment plan as received"
Who is right?
I have the totally same situation as topicstarter.
I filed taxes 2 weeks ago(with TurboTax) with requesting installment plan.But I still don't see any updates in my IRS account(I see only my old 2018 return).
Does that mean my return was not yet processed?
When it will be processed will I be able to see in my IRS account whether installment plan accepted or not?(it should be faster to know then wait mail notice).
What should I do if it will not be accepted? Take the loan to payoff tax debt? or any other options?
