Business & farm

I called the TurboTax Customer service at the link provided.  I allowed a rep to view my PC to see what I was asking to open my 2023 Desktop Business to see my 2023 1065 and 1041 tax returns. 

 

I purchased the 2024 Business Desktop product and downloaded the product.  I was asked which 2024 return I wanted to start and it gave me both the 2023 1065 and 1041 return options.  I selected the 1065 option and the applicable information from my 2023 return was downloaded to the 2024 return.   I completed the 2024 1065, submitted it to the IRS on 3/3/2025, and it was successfully accepted on 3/3/2025.  

 

I then attempted to start my 2024 1041 return although our calendar year runs from 8/1/2024 to 7/31/2025.  It asked me to "Choose file".  I don't have a file that has designated with .tax2023 as I apparently clicked on the link for saving as a pdf instead of the one for saving with .tax2023.  I choose the .pdf file I saved after submitting to IRS last August.  When I then attempted to open the 2023 return, TT stated they could not find the file and had a link to find the file.  I selected the back-up pdf and got this popup: "We’re having trouble opening your file.  You can try using your back-up file instead. You’ll find instructions on how to open your back-up file in the link below. Error: 102345"

 

The agent said that error code means the 2023 Business software is corrupted and I would have to completely manually input everything for my 2024 tax returns.  I had seen something that TT could download information from a pdf document from any source, such as H&R Block, Tax Act, etc.  However, it will not download the information from my pdf file I saved after submitting the returns. 

 

The error code has been around or years and I found a post from 2022 that appeared to say that undating the TT software may totally corrupt your returns.  I agreed to update the 2023 software when I opened it, which appears to be a mistake after filing. 

 

Is there any way to remove any updates done in 2025 for my 2023 completed in 2024?
