Military Retirement Pay Income Tax Deduction for Individuals who brought back military time and retired as civil servants (inquiry)

[wilonet]

I previously received the tax credit, as a retired military member until I combined my military time with my federal civilian time. I also previously received 2 1099r, for both my civilian and retired military pensions. I now only receive a single 1099 for my civilian and military retirement pays, that are now combined. How do I account for retired military tax credit on my tax paperwork, that I previously received before both of my retirement pensions were combined. I am also service connected, with a 100% permanent rating from the VA and I show, as a Veteran on my Md license but don't know how to get my tax credit without a 1099r from the Army.
