First, you had removed the oil drain line and oil feed line. The center housing with the bearings is also dry. If the oil feed line was bent or damaged, do not reuse it, get a new one or else the new turbo will have oil starvation.

Some ideas include using air pressure to push oil through the oil feed line, using vacuum to suck it through the drain line. Either way, (I'm assuming this is a PD TDI engine) make sure to unscrew the connector plug on the cylinder head to disable the fuel injectors. This will let you crank the engine and move some engine oil without starting the engine. Plug back in and once the engine is started, let it idle for a little bit before driving to get any remaining air out.

The factory service manual only says to "fill turbocharger with engine oil at oil supply connection". Obviously, this does not mean to fill the turbo housing with oil or it will be ingested or be blown out the exhaust. Also make sure you remove any rags that you stuffed in any lines.

The rag in the intake problem. I'm sure it happens more often than people would admit. Good warning.
