Your suggested manual update to TurboTax Business 2020, by way of the link provided and the subsequent "Manually Update TurboTax Business Software" page, did not fix the issue I am having. The update finally succeeded but did not solve my problem.
Please note that the initial try with the manual update failed with an error -- and I retried it about 5 times. I was left with TurboTax Business 2020 broken and unusable. I had to uninstall and reinstall TurboTax Business 2020 from the disc, and it was to this fresh installation that I applied the manual update finally with success.
To conclude, the manual update succeeded, but the problem with the Maryland 504NR form being "Ready Soon" remains. I am still unable to complete my return.
Is there another way to fix this issue?
