I started filling with h&rblock this year, well I decided to try turbo and I was rejected cause ss# have been used by me when I started h&rblock.what do I do? I need asap

Since I started with h&r block, can I go erase it? And come back to TurboTax, cause nobody has claimed my kids but me. And I'm late on bills I really can't wait until a check comes in. Please help me
