If you have funds, customer service can help you get the call approved. That is why I suggested you call them.
While you may have posted a deposit, I assure you, you have not yet been charged and I have not yet been credited with helping you.
There was a specific reason I suggested a call---primarily because you have posted 4 separate questions/issues in a single question thread. As you may not be aware, the Rules of JustAnswer specify that each customer ask one question in each question thread. For new questions/issues, the customer is asked to open a new question thread, or to accept an offer of additional services. I could answer all of your issued in 20 minutes or so on the phone, but due to the complexity of your issues, it could take me an hour or two to answer them all here.
You are asking about 4 separate things and their impact on social security benefits:
1. Disability Retirement
2. Workers compensation settlement
3. Retroactive wages.
4. When SSDI converts to Retirement benefits.
I can tell you that a private disability benefit you may be receiving will not impact your SSDI benefits.
Retroactive wages for time that you did not actually work, and a lump sum workers' compensation settlement both have the ability to impact your SSDI benefits.
