Sorry no. If you used the Desktop CD/Download program then the only copy is saved on your computer even if you efiled it. You should have a pdf file on your computer and saved to your backups. If you don't have the pdf file you also have the data file ending in .tax2018. Search your whole computer for the pdf and/or all files ending in .tax or .tax2018. They should be in your Documents then in a Turbo Tax folder. Did you use Windows or Mac?
