I filed with turbo in 2018 and 2019 but get my payment says payment status unavailable . Did my return get posted?

If you received an acknowledgement that your e-filed return was accepted, then the IRS has it. 

According to the IRS FAQs:

The Get My Payment application will return "Payment Status Not Available" for several reasons, including:

• You are required to file a tax return, but:
  • We haven't finished processing your 2019 return
  • The application doesn't yet have your data; we’re working on adding more data to allow more people to use it.
• You don't usually file a return, and:
  • You used Non-Filers: Enter Payment Info Here but we haven’t processed your entry yet
  • You receive an SSA or RRB Form 1099 or SSI or VA benefits; information has not been loaded onto our systems yet for people who don’t normally file a tax return.
• You’re not eligible for a payment (see Eligibility).

The IRS updates Get My Payment data once per day, overnight, so there is no need to check more often. If you are eligible for a payment and have provided your information either through a recent tax return or the Non-Filers: Enter Payment Info Here application, please check back for updates.
