2018 Extension filed with overpayment

I filed an extension for tax year 2018 with which I paid the estimated tax due - about $1750.

After gathering all the relevant documentation and other considerations, my tax due is under $300. 
The TurboTax desktop software (Mac version) requires that I file by mail and indicates that I must send a check. I presume that the desktop software is not connecting with the online software with which I filed the extension.

My understanding is that I am owed about $1450 as a tax refund. 
Any help is appreciated...
