I am assuming you are filing the 2018 for the first time. If that is the case, you must download the 2018 software it will not work using 2019 version for 2018.
For the 2019--Most likely it is getting rejected due to errors on your return.
If you are filing 2018, you will need to use the 2018 version of the software.
Once you enter your data there in 2018 software version....
Go through your return again on turbo tax in the step by step area. At the end, do a check for errors. If you have errors, you must correct them.
