Did you complete the Iowa return ? Did you get an efile confirmation that it was accepted for processing ?
Use this TurboTax website to check the status of an e-filed return and if it was either accepted or rejected -https://turbotax.intuit.com/tax-tools/efile-status-lookup/
If accepted by the IRS use the federal tax refund website to check the refund status - https://www.irs.gov/refunds
If accepted by the state use this TurboTax support FAQ to check the state tax refund status -https://ttlc.intuit.com/questions/1899433-how-do-i-track-my-state-refund
How do I print my federal tax forms?
Or have you confirmed you filed everything using the steps above and that all were accepted (if efiled), and are now merely wanting copies? Does the PDF you download only have one of the state returns? If that's the case, we can tell you how to open your return back up and get larger PDFs at the Print Center, and likely find the additional state return.
@mesquitebean My answer included the Print Center instructions.
